Competition Cams & Lifter Kits

comp cams logoHardin Marine has worked closely with Comp Cams to bring you the first camshaft design solely for marine applications, Xtreme Marine Camshafts are designed specifically for marine engines and their unique requirements. The small and mid-range cams are designed with cruising speeds and fuel economy in mind, while the big cams are designed for maximum power.

The smaller Xtreme Energy Cams are intended for applications where low idle speeds are required by the outdrive's transmission and where restrictive exhaust systems require special camshafts that work well against back-pressure typical in stock wet exhaust systems. These unique camshafts generate an extremely wide powerband, offering the low-end torque needed to jerk skiers up quickly or accelerate quickly out of the hole and the high speed power needed to be the fastest boat on the water.

hardin marine logoLarger Xtreme Marine Camshafts are engineered for engines with less restrictive exhaust systems and drives that will tolerate higher idle speeds. They're an excellent choice for jet boats or power boats with good through transom exhaust systems and/or up and over headers.

The largest of the family, the bad boys, are for engines with free flowing exhaust systems and special high RPM jet or outdrives. An excellent all-out cam when low-speed torque is less critical, they're for high RPM use only.

Xtreme Marine Camshafts are available for both Big and Small Block Chevy's and Big Block Fords, now even Oldsmobile's.
